Synthroid

Levothyroxine is a replacement for a hormone that is normally produced by your thyroid gland to regulate the body’s energy and metabolism. Levothyroxine is given when the thyroid does not produce enough of this hormone on its own. Levothyroxine treats hypothyroidism (low thyroid hormone). Levothyroxine is also used to treat or prevent goiter (enlarged thyroid gland), which can be caused by hormone imbalances, radiation treatment, surgery, or cancer. Levothyroxine should not be used to treat obesity or weight problems. Levothyroxine may also be used for other purposes not listed in this medication guide. Take levothyroxine exactly as your doctor has prescribed it for you. Do not use more of the medication than recommended. Do not take levothyroxine for longer than your doctor has prescribed. Your doctor may occasionally change your dose to make sure you get the best results from this medication. It is very important to take levothyroxine with a full glass (8 ounces) of water. The levothyroxine tablet can dissolve very quickly and swell in the throat, possibly causing choking or gagging. Take this medicine on an empty stomach, 30 minutes before eating. Levothyroxine is usually taken in the morning. Follow your doctor’s dosing instructions and try to take this medication at the same time each day. It may take several weeks before your body starts to respond to this medication.
